Answered Printer not feeding corectly

OK so i installed a new print head. I grabbed an e3d one, and yes it is a genuine one. So the printer worked flawlessly prior the swap. Now it seems to Stutter while feeding. I raised the head and set it to extrude 100 mm and marked out where 100 mm should be on the filament. It finished and i measured and came up 44.7 mm short of my mark. Am i having a calibration issue or is it something else. Please know that i am still pretty new to 3d printing. I will try and get a video up.

Thanks

 

Here is a video if it helps. You can see the pauses.

 

So as far as i can remember i followed the directions of someone on youtube. i can see if i can find the video i followed. I installed the bowden tube, and the video said i had to remove one of the plastic spacers that didnt quite fit with this head. Im not going to lie, i did it about 3 months ago before i moved and cant remember everything exactly. I now have time to get back into it and am looking to get it printing good again.

 

Yes i do have it installed.

 

OK so i finally got some time to work on the printer again. I attempted to see if i was extruding the correct amount. I set it to extrude 100 mm. I did it a couple time and for some reason i came up 41 mm short. So i read that i need to make an adjustment in Mater Control within the EEProm section. I'm not sure what field gets changed. Or you guys may tell me i am not doing the correct thing am that iI'm a total idiot.This is what i see.

Am i on the right track and what value do i change. Or should i go it in the G code. Any more help would be great. I would like to get back to printing.
